I'm trying to display customer details on screen from a file using
functions.

The details are written to the file first then I display them on screen
after I search for the file.

My problem is this:

I'm trying to display the details individually using this function for
void display();

All the other code is written I just need to get this function to run.

===============================================

void display()
{

char filename[15];
char in_char,ans;
int line;

do
{
clrscr();
cout<<"\nTo Display Contractor Details on the Screen";
cout<<"\nType the file name you want to see";
cout<<"\n\nEG. F:YOUR_FILE_NAME.txt :";
cin>>filename;

infile.open(filename, ios::in);
if(!infile)
{
clrscr();
cout<<"\n\n****That file does not exist****\n";
cout<<"Type F:\ and then up to eight letters for the file name,"
<<" then a dot and then three characters for the file type";
cout<<"\n\nEXAMPLE F:\THISFILE.TXT";
cout<<"\n\nDo you want to QUIT (Y/N)";
cin>>ans;
ans=toupper(ans);
}

}while((!infile)&&(ans!='Y'));

while(infile.get(in_char))
if (line>20)
{

cout<<(in_char);
cout<<"\n\nThat is the screen full...\n"
<<"\npress any key to clear it and continue...";
getch();
clrscr();

}
infile.close();

return;
}

===============================================

When I run this code it displays each character one at a time and not
the details.

The details are about 10 lines long and I need the program to say
"screen full" so that when I click continue the next set of details
comes up...

I been looking and trying everything for 3 hours now and I must be
missing something... can anyone point me in the right direction.

Thanks for your time.

Look at your variable line. Where do you give it a value? Answer,
nowhere. How does you problem say you need to read the file? Answer,
line by line. How do you read the file? Answer, character by character.

I don't know what you mean when you say that you must be missing
something, the problem is that your code bears no relation to the
problem you are trying to solve.
